The warn at line 20 in my program prints  <M> on its last 2 invocations, but not its first... why did this happen. Here is my program: 
use diagnostics; 
 
use String::Strip; 
 
my @unix_file = 'churn-list.dat'; 
 
my @ms_file = <*.rpt>; 
 
warn "UNIX"; 
 
`cat $_`     for (@unix_file); 
 
warn "WIN32"; 
 
 
for (@ms_file) { 
    warn $_; 
    proc_ms($_); 
} 
 
sub proc_ms { 
 
    my $file = shift; 
 
    open (M, "tail +3 $_ |") or die $!; 
 
    while (<M>) { 
        last if /^\s*$/; # the line before X rows affected 
        my ($id, $email) = split; 
        StripTSpace($email); 
        print "$id\t$email\n"; 
    } 
 
}
